Pallet carrier

Claim 2

An open frame carrier adapted to be suspended from the bottom of a semi-trailer forward of the rear wheels for transporting pallets or the like, the carrier comprising a support frame having a width approximating the width of the trailer and a plurality of support bars secured to and extending upwardly from the support frame, the bars being arranged in transverse rows across the width of the support frame and each including connection means on the upper end for attaching the bar to the bottom of the trailer, the rows of bars being spaced along the front-to-back length of the support frame to define a plurality of bays opening on both sides of the carrier, the support frame including longitudinally extended outer rails, a center rail located below the outer rails and a plurality of transversely extending support bars joining the outer rails and center rail so that the support bars angle downwardly from the outer rails to the center rail to aid in retaining pallets or the like in the bays, each bay including at least two spaced support bars for supporting a plurality of pallets or the like loaded in the bay, means for selectively opening or closing the bays on the lateral sides of the carrier to permit either loading, unloading or retention of pallets or the like into or from the bays, and a first stiffening member secured at a lower end to the support frame and angling upwardly to an upper end adapted to be secured to the bottom of the trailer to stiffen the carrier against front and back movement and a second stiffening member secured at a lower end to the support frame and angling upwardly therefrom across the width of the carrier to an upper end permanently secured to stiffen the carrier against lateral movement.

Claim 3

A carrier as in claim 1 wherein the lower ends of the support bars are attached to the outer and center rails, and lateral rows of support bars are provided at the forward and rear ends of the rails.

Claim 4

A carrier as in claim 2 wherein the rows of support bars between adjacent bays are formed of strip stock, the major faces of the strip stock facing forwardly and rearwardly to maximize bay width.

Claim 5

A pallet carrier as in claim 1 including an aerodynamic wing at the forward end of the carrier extending across the width and height of the carrier, the wing including a pair of vertical deflecting wing sections each extending inwardly and forwardly from one forward side of the carrier and joining a central vertical apex.

Claim 6

A carrier as in claim 4 including a set of struts joining each wing section and the apex of the wing to a support bar.

Claim 7

A carrier as in claim 5 wherein the central apex is rounded and the wing is formed from a single metal sheet.

Claim 8

An open frame carrier adapted to be suspended from the bottom of a semi-trailer forward of the rear wheels for transporting pallets or the like, the trailer including at least one exposed I-beam extending across the width of the bottom thereof, the carrier comprising a support frame having a width approximating the width of the trailer and a plurality of support bars secured to and extending upwardly from the support frame, the bars being arranged in transverse rows across the width of the support frame and each including connection means on the upper end for attaching the bar to the bottom of the trailer, the rows of bars being spaced along the front-to-back length of the support frame to define a plurality of bays opening on the sides of the carrier, longitudinally extending outer rails, a center rail located below the outer rails and a plurality of transversely extending support bars joining the outer rails and center rails so that the support bars angle downwardly from the outer rail to the center rail to aid in retaining the pallets or the like in the bays, each bay including at least two spaced apart support bars for supporting a plurality of pallets or the like loaded in the bay, means for selectively opening or closing the bays on the sides of the carrier to permit loading, unloading or retention of the pallets or the like into or from the bays, the connection means on the upper ends of at least one row of bars including a bore extending through the upper end of each support bar, a spacer for each bar having a thickness equal to or greater than the depth of the channel on one side of the I-beam and fitted within such channel so that an outer support surface thereon is flush with or outwardly of the lower I-beam flange, the bore extending through the spacer and the web of the I-beam, and a nut and bolt with the bolt extending through the bore threaded to the nut thereby securing the bars to the beam.

Claim 9

An open frame carrier adapted to be suspended from the bottom of a semi-trailer forward of the rear wheels for transporting pallets or the like, the trailer including at least one exposed I-beam extending across the width of the bottom thereof, the carrier comprising a support frame having a width approximating the width of the trailer and a plurality of support bars secured to and extending upwardly from the support frame, the bars being arranged in transverse rows across the width of the support frame and each including connection means on the upper end for attaching the bar to the bottom of the trailer, the rows of bars being spaced along the front-to-back length of the support frame to define a plurality of bays opening on the sides of the carrier, longitudinally extending outer rails, a center rail located below the outer rails and a plurality of transversely extending support bars joining the outer rails and center rails so that the support bars angle downwardly from the outer rail to the center rail to aid in retaining the pallets or the like in the bays, each bay including at least two spaced apart support bars for supporting a plurality of pallets or the like loaded in the bay, means for selectively opening or closing the bays on the sides of the carrier to permit loading, unloading or retention of the pallets or the like into or from the bays, the connection means on the upper ends of at least one row of bars including a bore extending through the upper end of each support bar, a spacer for each bar having a thickness equal to or greater than the depth of the channel on one side of the I-beam and fitted within such channel so that an outer support surface thereon is flush with or outwardly of the lower I-beam flange, the bore extending through the spacer and the web of the I-beam, and a nut and bolt with the bolt extending through the bore threaded to the nut thereby securing the bars to the beam.

Claim 10

A carrier as in claim 7 wherein the trailer includes at least two exposed I-beams extending across the bottom thereof and two rows of bars secured to the I-beams by connections like said connection means, the spacers of the connection means of one row of bars being thicker than the spacers of the connections means for the other row of bars.

Claim 11

A carrier as in claim 7 including rows of support bars at the front and back of the support frame, the trailer includes beams adjacent each rows of bars and the bars of said rows, are attached to the beams by connections like said connection means with the beams on the inside of the bars.

Claim 12

A carrier as in claim 7 including four rows of support bars, the trailer including a beam for each row of bars, connections like said connection means attaching the bars to said beams with the beams on the inside of the bars of each row and the spacers for the end rows of bars being thicker than the spacers for the interior rows of bars.

Claim 13

A carrier as in claim 10 including stiffening means for resisting fore and aft movement of the carrier and stiffening means for resisting lateral movement of the carrier, each of such means including an upwardly angled structural member.
